Bring a medium pot with 3 cups of water to a boil. Thoroughly rinse produce and pat dry. Stem cilantro. Stem and slice mushrooms into 1/4" strips. Halve lime. Trim root end of baby bok choy, then cut into quarters lengthwise. Slice red Fresno chile into thin rounds. Cut lemongrass in half lengthwise. Be careful - lemongrass is very tough! Trim and thinly slice green onions on an angle (bias). Rinse salmon and pat dry.

Reduce boiling water to a simmer and add vegetable base, lemongrass, half the green onion, half the cilantro, juice of the lime (reserving a small bit of juice for garnish), soy sauce, half the Fresno chile (to taste), and chopped ginger. Simmer for 10 minutes.

Heat a medium pan over medium heat. Add 1 Tbsp. olive oil and mushrooms and cook 4-5 minutes, or until browned. Season with a pinch of salt and pepper. Transfer to a plate and set aside. Wipe pan clean.

Return pan used for mushrooms to medium-high heat. Season salmon with a pinch of salt and pepper. Add 1 tsp. olive oil to pan and cook salmon on each side for 4-5 minutes, or until browned, firm, and a minimum internal temperature of 145 degrees is reached.

Bring broth to a low simmer. Add baby bok choy (reserve a few leaves for garnish) and let wilt for 1-2 minutes before serving.

Ladle broth with bok choy into a bowl. Add sautéed mushrooms and reserved bok choy leaves to the bowl. Add salmon, garnish with remaining Fresno chile (to taste), remaining cilantro, and remaining green onions. Finish with a squeeze of lime juice.
